Physical Therapy and Rehabilitation After Hip and Knee Replacement
Hip and knee joint diseases are among the primary problems that significantly reduce patients’ quality of life for many years. In cases where conservative treatment methods remain insufficient, surgical intervention becomes inevitable. At this point, hip replacement or knee replacement surgery stands out as the most effective solution for patients to regain their mobility.
Why is the post-operative recovery process so important?
Following replacement surgery, the vast majority of patients face difficulties in returning to their daily lives. This difficulty is felt more prominently, especially in elderly individuals. Pain, swelling, and joint inflammation (inflammation) in the surgical area can prolong the healing process. Although it is possible for young patients with sufficient muscle strength to return to activities such as walking and even light jogging relatively quickly, every patient experiences this process differently.
Physical Therapy and Rehabilitation: The Key to Recovery
To solve the problems of pain, soreness, and restricted movement that arise after surgery, physical therapy and rehabilitation is the most fundamental supportive treatment method. Patients can carry out this process in two different ways:
- Clinical rehabilitation: Receiving professional physical therapy by going to a health center as an inpatient or outpatient.
- Home exercise program: Individual application at home with exercises prepared under the supervision of a doctor and physiotherapist.
Gait Robot in Rehabilitation
In modern physical therapy centers, gait robots have become an integral part of prosthesis rehabilitation. While in traditional walking exercises the patient tries to take steps in parallel bars or with walker support accompanied by a physiotherapist, robotic walking systems move this process to a much more controlled, safe, and measurable ground. Especially in the early post-operative period for patients who cannot yet fully stand up, gait robots pave the way for starting rehabilitation early.
These devices help the patient regain the ability to walk step-by-step by meticulously taking into account the movement angles allowed by the installed prosthesis. Thanks to software-supported sensor systems, the force, angle, and movement speed applied at each step are monitored instantaneously and adjusted automatically when necessary. This level of precision ensures that the prosthesis functions in the correct position and prevents overstraining of the surrounding tissues.
Controlled movement performed at the correct angles not only supports the long-lasting use of the prosthesis but also sets the stage for strengthening the muscles around the hip and knee that weakened after surgery. As muscle activation increases, balance improves, the risk of falling decreases, and the patient returns to daily life activities much more safely. The realization of all these effects together significantly shortens the patient’s total rehabilitation period and contributes to shorter hospital stays.
In addition, gait robot applications create a positive effect on the patient’s motivation. The number of steps, balance score, and progress graphs followed instantaneously on the screen allow the patient to tangibly see their own healing process. This feedback mechanism is an important factor that increases patients’ commitment to treatment, especially during a long and challenging rehabilitation period.
Regaining Range of Motion with CPM
One of the most common rehabilitation methods applied immediately after replacement surgery is the CPM (Continuous Passive Motion) device. Without the patient exerting any muscle strength, the operated joint is moved slowly and in a controlled manner with the help of the device. In this way, hardening of the joint capsule is prevented, blood circulation is supported, and the risk of deep vein thrombosis (clotting) is reduced. The CPM device is generally applied in a sitting position in bed or on a chair; active participation of the patient is not required. It is an extremely valuable tool in terms of rapidly restoring joint range of motion, especially in the early period after knee replacement.
Electrotherapy: Reduces Pain, Accelerates Healing
Electrotherapy is a method frequently used for pain management and muscle activation in prosthesis rehabilitation. Different electrotherapy modalities such as TENS (Transcutaneous Electrical Nerve Stimulation), EMS (Electrical Muscle Stimulation), and interferential current are selected by the physiotherapist according to the patient’s condition. While TENS application suppresses post-operative pain, EMS helps to reactivate muscles that weakened during the surgical process. Ultrasound and laser therapy are also among the electrotherapy applications that support tissue healing. This method, which minimizes drug use, offers a preferable alternative, especially for elderly patients and those using numerous medications.
Balance Training with the Tilt Table
For patients who stay in bed for a long time or have difficulty standing up after surgery, the tilt table forms a critical link in rehabilitation. Starting from a horizontal position, the table is tilted gradually towards a vertical position; thus, the body is accustomed to the gravity load of standing and changes in blood pressure in a controlled environment. In patients experiencing dizziness, low blood pressure (orthostatic hypotension), and balance problems, the tilt table application functions as a safe transition bridge before independent standing and walking. Supporting early mobilization after prosthesis, this method is applied carefully and under expert supervision, especially in elderly individuals and those with cardiovascular risks.
Hydrotherapy: Rehabilitation with the Healing Power of Water
Hydrotherapy (in-water exercise therapy) is an innovative method increasingly preferred in prosthesis rehabilitation. Thanks to the buoyancy of water, the load on the joints is significantly reduced; this allows the patient to perform movements that they could not do on land in a painless manner. Exercises performed in a heated pool environment relax the muscles, increase blood circulation, and reduce swelling. At the same time, muscle strength is gradually rebuilt thanks to the resistance of water. Hydrotherapy gives confidence to the patient both physically and psychologically; entering the water increases their motivation for rehabilitation by reducing the patients’ fear of walking and expectation of pain.
